Can’t wait till NASA makes 4K (or even 8K) video the standard for satellite videos. Storage volumes have dropped way down in price and the taxpayer money in their pockets can pay for higher res in a New York minute.
I suggest not only clicking on the “expand” icon in the lower RH corner as soon as you start the video running; but, then, move a jot to the left and click the gear shape for settings. No need to change resolution; but, you can reduce playback speed and slow down the pan speed. Way cool! I usually run it at 0.5.
